Описание

In the Linux kernel, the following vulnerability has been resolved: NFS: Pin the 'struct nfs_server' during a FREE_STATEID call Dan Aloni reports that he was able to hit a use-after-free bug if a FREE_STATEID operation gets delayed for whatever reason. Fix this by bumping the refcount of the 'struct nfs_server' object for the duration of the FREE_STATEID so it doesn't get cleaned up from underneath us while operations are still in flight.

A flaw was found in the Linux kernel's Network File System (NFS). This vulnerability involves improper memory handling where a critical data structure is released prematurely if a FREE_STATEID operation is delayed. This can lead to memory corruption, potentially causing system instability or a denial of service.
